LEON K. BELCHER, OF NEW YORK, N. Y.

OIL-BURNER.

Too whom as may concern:

Be it known that 1, Leon K. BnLoueu. a citizen of the United States,residing at New York, in the county and State of New York, have inventedcertain new and useful Imirovements in Oil-Burners, of which theollowing is a full, clear, and exact specification.

This invention relates to oil vapor burnera, and one object is tosimplify the construction of such burners by casting, the same in anintegral piece.

Another object is to improve the heating rower oi the burner andeliminate. smoke JY providing a blue flame. It is also the ann of thisinvention to provide means for regulating the size of the flame andthereby, control the heat generated. A further object is to produce aburner with a plurality of flame jets, with means for cutting off thegas to one or more of the jets while one or.niore of the other jets arebeing used. Other objects will appear a the description proceeds. V

."he invention will he lil.\l lu-reiuaftcr de bed in connection with theaccompanyili}"dran'ings, which constitute part of this specification.and then more specifically de fined in the claims at the end of thedescription.

In the accompanying drawings, in which similar reference chara ters areused to designate corresponding parts throughout the several viewsFigure 1 is an end elevation of a lnirner constructed substantially in:uzcordancc with this invention.

Fig. 2 is a section on the line IL-ll of Fi I 1 2. I n'stead of theseveral pipes and connect mg elbows enerally used in constructma burnersof t is class. an integral casting 1 is used in this case, the samebeingapproximately rectangular in shape Wli'll an upper horizontal portion 2.a lower horizontal portion 3, and vertical end portions 4 and 5. Theupper horizontal portion 2 has two 1ongitudinal bores 6 and 7 which areconnected y a. cross bore 8 at one end. The other end of the bore 6communicates with a nipple 9 designed to be attached to any source ofoil supply, while the other end of the Specification of Letters Patent.

bore 7 communicates with a bore 10 1n the end portion 5 of thecasting 1. The lower horizontal portion 3 has a single. longitudinalbore 11 which communicates with the bore 10.-

The burners proper 12 are dotachablv connected to the under face of theupper horizontal portion 2 of the. casting preterably by means of thesliding; dove-tail joints 13 best illustrated in Fig. 3. which permitssaid burners to be removed for cleaning. repairing or adjustment. Eachburner comprising a funnel shaped luul) member 14 having a horizontalannular flange 15 at its upper end. and a disk 16 to lit said flange andadjustably conr ctcd thereto by bolts 17. The upper face of the flange1:: is dished at i and the disk is correspondingly dished at 19 so thatthe faces thereof which are presented to each other are parallel. ]lmeans of the bolts 17 the space between the [tango 15 and disk 16 may bevaried to decrease or increase the size of the flame which in use isformed around the top of the burner. l'lach burner is arranged directlyover an opening 20 in the lower por tion 3 of the casting". Theseopenings 20 connnunicate with the bore 11 and are 1irected upwardly sothat the gas which issues therei'rom is projected into the conical orfunnel-shaped passage in the body member 11 of the burner. Owing to theshape of these passages the pdssage of the gas therethrough draws in airwith it so that the flame which issues around the top of the burner fromthe space between the flange 15 and disk 16 is a smokeless blue flamecapable of generating a maximum heat. This flame is positioned closebelow the upper portion 2 of the casting, thus insuring against waste ofthe heat enerated.

In operation. the oil which is admitted at the nipple 9 passes throughthe bore 6 over the burners. and then back over them again through thebore 7 Both of these bores are filled with rods 21 which serve to breakup the oil andgreatly help in vaporizing it. From the bore 7 thevaporized fucl passes down through the bore 10 to the bore 11 from whichit issues through the openings 20 to the burners.

A. vahe 22 is provided in the bore 11 between the openings 20, sothatone burner ii he bore 7.

from the other. Of course, this valve may be opened and both burnersneed together when desired.

When the oil Suppl is first turned on, a small quantity of in aminablematerial is placed in the bells 23 which are supported from the underface of the lower portion. 3 of the casting. This inliannnable materialis ignited and the flame therefrom will act in place of the flames fromthe burners to vaporize theoil 'in the bores 6 and 7. The several boreson the casting-are provided with removable plugs 24 at their ends to)ermit cleaning, the introduction of the fill ing rods 21, and otherpurposes.-

Thecaeting 1 preferably has depending portions 25 below. the lowerllmlZOlltnl por-- tion 3 for supporting the device in operativeposition. The bore 6 may be termed the gas generating chamber, and thebore 7 may be called the gas drying and expansion Lililflh her, for theoil is vapor" ed in the bore 1.; id is further dried an allowed toexpand Having thus described my invention, what I claim as new anddesire to SQUlllu. by Letters Patent of the United States is:

1. An oil burner of the character described having a gas generatingchamber, a burner having sliding interlocking connection With the undersurface of the chamber, and means having a gas generating chamber, aburner for supplying gas from said chamber to the burner.

2. An oil burner of the character described below said chamber, said biuner comprisin r a conically bored body portion and a disc covorin thesame, and body portion and disk being dished and having their facingsurfaces parallel, means for retaining. the disk in spaced relation tothe body Jortion for providing an annular opening; or the limingnildd'llmlllfi for supplying gas to the burner from the gas generatingchamber.

3. An oil. burner of the character described having a gas generatingchamber, a burner below said chamber, said burner comprising a(sonically bored body portion and adisk for coverin the same,slidinginterlocking connection getween the disk and the under surface ofthe generating chamber, adjust able means of connection between the dishand body portion for roviding a variable annular opening for 1; ie'liainc. and means for supplying gas to the body portion of the burnerfrom said generating chamber.

4. A. burner comprising a body portion having a central bore, a diskcovering the bore at the top of the body portion, and means forretaining thedisk in "epaced relation to the body portion for providingan annular fiaine o ening around the top of the burner, saiddisi: beingdished over the bore. and the top of the body portion beingcorrespondingly concaved for the purpose specified.

In testimony whereof I have signeddn name to this specification.
